After Delenn mentioned that the developer of Immortal Defense was looking for beta testers (I think), they kindly game me a Steam key to check the game out.
Unfortunately I actually lost track of the game (couldn't remember its name and had been intending to ask Delenn to remind me as I felt a little disappointed in myself for not giving much feedback, Anyway, I rediscovered it yesterday after searching through the giveaway game discussion forums for a particular thread i posted a few years ago and was wondering why it had been removed from Steam?
I know the dev's had been working on the game for well over a decade and I was really impressed with the early access version when I checked it out.
